Former NFL player plans to open pot-friendly gym

Members must have prescription to join

Ricky WilliamsFacing a four-game suspension after testing positive for marijuana use, the Heisman Trophy winner and Miami Dolphins running back abruptly retired from the NFL in 2004, instead studying Ayurveda, the ancient Indian system of holistic medicine, at the California College of Ayurveda that fall. He returned to the Miami Dolphins in July 2005, paying back a percentage of his signing bonus and completing his original four game suspension. After being suspended for another NFL drug policy violation in 2006, he played for the Canadian Football League's Toronto Argonauts before returning to the Dolphins for 2007-10.

Former NFL running back Ricky Williams and business executive Jim McAlpine have plans to open the world's first pot-friendly gym, The Associated Press reports.

The gym, Power Plant Fitness, will allow people to not only smoke marijuana during a workout, but will also have edibles available for those who don't like smoking. The men say that using pot while exercising can help with focus and relaxation.

Pending California's vote later this year to legalize recreational use of the plant, gym-goers will need to have a prescription for marijuana in order to join.

"I think a lot of people buy into the stoner stereotype where guys just sit on the couch, smoke and don't do anything, and they're not very motivated," said Williams. "I found when I was playing football that using cannabis helped me relax physically, relax mentally and even spiritually."
